  • Primary cardiac fibroma of the left ventricular myocardium is a rare tumor of the heart which is usually located within the anterior wall and /or septum of the left ventricle and is the second most common cardiac tumor in infant and children. Although the tumor is benign histologically, it may cause severe cardiac dysfunction and sudden death. A 30-day-old neonate with a huge intramural fibroma involving the posterolateral wall of the left ventricle underwent it`s partial resection under extracorporeal circulation on April 1992.

  • In this study, we present the computational analysis of cardiac arrhythmias that is the major cause of human sudden cardiac death. First, electric excitation and condution in one dimensional cardiac tissue model is solved and the results on condution block are represented. In two dimensional model, vortex daynamics in cardiac tissue is analyzed to delineate the breakup phenomenon inducing ventricular fibrillation. We also simulated a three dimenional heart model to see the vortex breakup and explained the mechanism in physiological aspect.

  • The author conducted a literature review to better characterize the current state of knowledge regardeding the relationship between psychological and behavioral factors and cardiovascular disease. This review focus on several Problems : hypertension, coronary artery disease such as myocardial infarction and angina pectoris, sudden death, arrhythmia, vasomotor(vasodepressor) syncope, and psychogenic cardiac nondisease. We describe model for understanding the relationship of psychological factors to the disease, review the results of relevant research studies and provide recommendation for further research.

  • Aortic dissection is an uncommon, life-threatening medical emergency that is associated with a high mortality rate, and death from aortic dissection is mainly related to secondary complications, namely cardiac tamponade, severe aortic regurgitation, acute myocardial infarction, and abdominal organ vessel obstruction. Hence, prompt and accurate diagnosis followed by proper treatment is important for patient survival. Herein, we present a rare case of sudden death after aortic dissection with concomitant acute myocardial infarction and cardiac tamponade.

  • Magnetocardiography (MCG) is the measurement and analysis of the magnetic component of the electro-magnetic field of the human heart, usually conducted externally, using extremely sensitive devices such as a Superconducting Quantum Interference Device (SQUID). MCG is a totally noninvasive method, it uses neither radiation nor ultrasonics. The magnetic activity of the heart is registered from outside the thorax. MCG has a very high sensitivity and a high spatial resolution for very a small, local myocardial current. In comparison to the electrical signals measured by an ECG, the magnetic signal does not disturb the boundaries of tissues with different electrical properties. MCG measures the myocardial function rather than describing the morphology. MCG is a relatively new technique that promises good spatial resolution and extremely high temporal resolution, thus complementing other heart activity measurement techniques such as Electrocardiography (ECG). The clinical uses of MCG are in detecting various cardiac disorders including myocardial infarction, ventricular hypertrophy, ventricular conduction defects, Wolff-Parkinson-White (WPW) syndrome, sudden cardiac death and fetal magnetocardiography. Magnetocardiography may be used alone or together with electrcardiography for the measurement of spontaneous or overloaded activity and for research or clinical purposes.

  • Anomalous origin of the coronary artery from the pulmonary artery is a rare and potentially fatal congenital heart defect. Up to 90% of infants with an anomaly involving the left coronary artery die within the first year of life if left untreated. Patients who survive beyond infancy are at risk of sudden cardiac death. Cardiac CT and MRI are increasingly being used for the accurate diagnosis of this anomaly for prompt surgical restoration of the dual coronary artery system. Moreover, life-long imaging surveillance after surgery is necessary for these patients. In this pictorial review, multimodal cardiac imaging findings of this rare and potentially fatal coronary artery anomaly are comprehensively discussed, and representative images are provided to facilitate the understanding of this anomaly.

  • Cardiac fibroma is a rare benign tumor of the heart that occurs primarily in infants and children. Prognosis depends on size, extent and site of tumor. Cardiac fibroma may invade the conduction system, papillary muscle and outflw of inflow tract of ventricle. In these situations, its clinical course is very poor Although operative mortality is high, surgical resection is treatment of choice because lethal arrhythmia and sudden death can be developed by the fibroma. A cardiac fibroma was successfully resected from the left ventricular myocardium of a 8 years old male patient in the Department of Thoracic and Cardiovascular Surgery, Chonbuk National University Hospital.

  • Progressive muscular dystrophy (PMD) is a primary muscle disease characterized by progressive muscle weakness and wasting, which is inherited by an X-linked recessive pattern and occurs mainly in males. There are several types of muscular dystrophies classified according to the distribution of predominant muscle weakness including Duchenne and Becker, Emery-Dreifuss, facioscapulohumeral, oculopharyngeal, and limb-girdle type. Clinical manifestations of PMD are clumsy, unsteady gait, pneumonia, heart failure, pulmonary edema, hydropericardium, hydrothorax, aspiration, syncopal attacks, and sudden cardiac death. The deceased was a 34-year-old man, and the onset of the first clinical symptom, gait disturbance, was in his late teens. His elder brother had the same disease and experienced brain death after a head trauma and died after mechanical ventilation was discontinued. After an autopsy, we found contracture of the joints, pseudohypertrophy of the calf, wasting and fat replacement of the thigh muscle, pericardial effusion (80 mL), fibrosis and fat replacement of the cardiac ventricular wall, pulmonary edema, and froth in the bronchus. The cause of death was heart failure and dyspnea due to muscular dystrophy. There was no sign or suspicion of foul play in his death.

  • Transposition of the great arteries is one of the commonest forms of severe congenital heart disease and produces severe cyanosis threatening survival from the day of birth. Anatomical anomalies which the aorta arises from the infundibulum of the right ventricle and the pulmonary artery arises from the outflow tract of the left ventricle make the deranged circulation. Survival is possible only if additional anomalies are present which allow mixing of the pulmonary and systemic circulations. Preoperative diagnosis as TGA was taken on the 15 day old female via the preoperative examination and the right cordioangiography. As palliative treatment for cyanosis, Blalock-Hanlon operation was performed in this patient. The results were good as 54 mmHg changed from 27 mmHg of $PO_2$ in aorta, but sudden cardiac arrest was developed in postoperative 12 hours. In order to confirm the cause of death and the cardiac anomalies, autopsy was performed on the date of death. The diagnosis of the autopsy showed; [1] Transposition of the Great Arteries. [2] Patent Ductus Arteriosus. [3] Patent Foramen Ovale. [4] Ventricular Septal Defect, 2 Muscular Type. [5] Double Ureter, Right. [6] Artificial Atrial Septal Defect. [7] Total Collapse of the left lung and Intraparenchymal hemorrhage of right lung.
